Abstract (en)
[origin: WO2011080405A1] The invention relates to removing acid compounds from a gaseous effluent in an absorption process implementing an aqueous solution containing one or more diamines, of which the two amine functions are not interconnected by rings and of which the a position amine function is always tertiary and of which the ? position amine function is always either primary or more or less sterically congested secondary, and which satisfies the following general formula (I).
